Glitches

Select your oppositions lineup/pitchers

Scroll to the left when adjusting your lineup, and you can replace the starters in your opponents lineup that might be real good, or have a certain advantage against your pitcher with bench players that probably aren't as good as the starters.

Also, you can choose your opponents starting pitcher by scrolling left on the screen where you can select your pitcher, and you can select a pitcher that might have lower stamina, or is just really bad.
